The CPU has an integrated memory. Information about the capacity of the memory may
be found at the front of the CPU. The memory is divided into the following parts:
n
Load memory 4Mbyte
n
Code memory (50% of the work memory)
n
Data memory (50% of the work memory)
n
Work memory 1Mbyte
–
There is the possibility to extend the work memory to its maximum printed
capacity 4Mbyte by means of a memory extension card.
The CPU has a PROFIBUS/PtP interface with a fix pinout. After an overall reset the inter-
face is deactivated. By appropriate configuration, the following functions for this interface
may be enabled:
n
PROFIBUS DP master operation: Configuration via PROFIBUS sub module with
‘Operation mode’
master in the hardware configuration.
n
PROFIBUS DP slave operation: Configuration via PROFIBUS sub module with
‘Operation mode’
slave in the hardware configuration.
n
PtP functionality: Configuration as virtual PROFIBUS master system by including the
Yaskawa SPEEDBUS.GSD.
The CPU has an integrated PROFINET IO controller which is to be configured via the
PROFINET sub module in the hardware configurator from Siemens.
The CPU has an Ethernet interface for PG/OP communication. After assigning IP
address parameters with your configuration tool, via the "PLC" functions you may directly
access the Ethernet PG/OP channel and program res. remote control your CPU. You may
also access the CPU with a visualization software via these connections.
n
Wiring by means of spring pressure connections (CageClamps) at the front connector
n
Core cross-section 0.08...2.5mm

n
Total isolation of the wiring at module change
n
Potential separation of all modules to the backplane bus
Dimensions of the basic enclosure:

2tier width: (WxHxD) in mm: 80x125x120
The CPU comes with an integrated power supply. The power supply is to be supplied with
DC 24V. By means of the supply voltage, the internal electronic is supplied as well as the
connected modules via backplane bus. The power supply is protected against inverse
polarity and overcurrent.
